What This Code Means
M61.379 is the ICD-10-CM diagnosis code for calcification and ossification of muscles associated with burns, unspecified ankle and foot. Hardening and bone formation in muscles of the ankle and foot as a result of burn injury, when the specific side is not documented or cannot be determined. M61.379 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of muscles (m60-m63).
M61.379 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
